摘要：
New artemisinin tricyclic analogs, bearing a methyl group at C-5a were synthetized through ozonation of vinylsilanes. Presence of such a substituent was detrimental to the antimalarial activity of these trioxanes, thus reinforcing the hypothesis that tight hemin-trioxane complexes are involved in the activation phase of these compounds.
